# 前端開發模式 用於 React、Next.js 和高效能使用者介面的現代前端模式。 ## 元件模式 ### 組合優於繼承 ```typescript // PASS: 良好：元件組合 interface CardProps { children: React.ReactNode variant?: 'default' | 'outlined' } export function Card({ children, variant = 'default' }: CardProps) { return <div className={`card card-${variant}`}>{children}</div> } export function CardHeader({ children }: { children: React.ReactNode }) { return <div className="card-header">{children}</div> } export function CardBody({ children }: { children: React.ReactNode }) { return <div className="card-body">{children}</div> } // 使用方式 <Card> <CardHeader>標題</CardHeader> <CardBody>內容</CardBody> </Card> ``` ### 複合元件 ```typescript interface TabsContextValue { activeTab: string setActiveTab: (tab: string) => void } const TabsContext = createContext<TabsContextValue | undefined>(undefined) export function Tabs({ children, defaultTab }: { children: React.ReactNode defaultTab: string }) { const [activeTab, setActiveTab] = useState(defaultTab) return ( <TabsContext.Provider value={{ activeTab, setActiveTab }}> {children} </TabsContext.Provider> ) } export function TabList({ children }: { children: React.ReactNode }) { return <div className="tab-list">{children}</div> } export function Tab({ id, children }: { id: string, children: React.ReactNode }) { const context = useContext(TabsContext) if (!context) throw new Error('Tab must be used within Tabs') return ( <button className=...
